The World Chess Federation, FIDE (Fédération Internationale des Échecs), awards several performance-based titles to chess players, up to and including the highly prized Grandmaster title. Titles generally require a combination of Elo rating and norms (performance benchmarks in competitions including other titled players). Once awarded, FIDE titles are held for life, though a title may be revoked in exceptional circumstances.[1] Open titles may be earned by all players, whilst the women's titles are restricted to female players. A strong female player may have a title in both systems.
